建筑结构钢领域重点技术发展与布局☆
Development and Distribution of Key Patent Technologies in the Field of Constructional Structural Steels
[目的/意义] 近年来,钢结构建筑的飞速发展引发了对建筑结构钢技术领域的重点关注。对比总结该领域国内外机构的技术布局特征,可为我国的技术研发布局提供重要参考。[方法/过程] 利用专利分析与文献综述的方法,从专利申请态势、国内外优势机构及其重点技术等方面进行梳理,细致分析了建筑结构钢技术领域的总体发展趋势,包括优势机构的关键专利在建筑结构钢的组成结构及加工过程、功能性以及焊接方法等技术领域的发展轨迹。[结果/结论] 日本和韩国在该技术领域的实力更为突出,中国的研发起步较晚,特殊性能建筑结构钢的研发不足且技术分散,需加快建立多元化产业链,进一步拓展国际市场。
[Objective/Significance] In recent years, it has aroused the key attention in the technical field of constructional structure steel industry with the rapid development of steel structure. [Method/Process] Using the methods of patent analysis and literature review, the overall development trend of the technical field of constructional structural steel was analyzed in detail from the aspects of patent application situation, advantageous institutions at home and abroad, and their key technology development. The contents of analysis mainly included the development track of the key patents of advantageous institutions in this field, such as compositions and structures, processing process, functionality and welding methods. Based on the obtained results, the technical characteristics of domestic and foreign institutions were compared and summarized, which may provide instructive inspirations for the technical R&D layout of related institutions in China. [Results/Conclusions] Japan and South Korea are outstanding in the technology, while the R&D started relatively late in China. The technology of special performance building structural steel is insufficient and scattered. It is necessary to accelerate the establishment of a diversified industrial chain,and expand international market furtherly.
